Well, there's the DISK-IO MIB in SNMP..  on my box it's
/usr/share/snmp/mibs/UCD-DISKIO-MIB.txt

Have you considered using SNMP already?

Using that with MRTG and maybe some outside tools (you could write a
script that returns a number for MRTG to graph) you may be able to
accomplish a fair amount of what you're going for.
